2004-08-15 · This study evaluates the long-term clinical outcome of 56 consecutive patients affected by atrial fibrillation and drug-related typical atrial flutter who underwent cavo-tricuspid isthmus radiofrequency ablation. Symptomatic arrhythmic events recurred after ablation in 64% of the patients during follow-up of 19 ± 9 months. It has been demonstrated that successful cavotricuspid isthmus ablation of typical atrial flutter combined with atrial fibrillation (AF) sometimes influences the preablation history of paroxysmal AF. However, the effectiveness of only isthmus ablation on AF itself is unclear. Introduction. PVI is a well-established therapy for patients with drug refractory atrial fibrillation (AF).
[citation needed] Management. In general, atrial flutter should be managed the same as atrial fibrillation. Atrial fibrillation (AF) is a common finding in patients undergoing cavotricuspid isthmus ablation for isthmus dependent right atrial flutter (RAF). Little is known about the time of its occurrence.
Ablation of Atrial Fibrillation at the Time of Cavotricuspid Isthmus Ablation in Patients With Atrial Flutter Without Documented Atrial Fibrillation Derives a Better Long-Term Benefit Article Jan 2011
1–3 However, patients also may experience typical atrial flutter arising from the cavotricuspid isthmus (CTI) after ablation of AF. 4 Because LA ablation may alter the normal activation pattern of the LA, 2 it is possible that the 12-lead ECG of CTI-dependent flutter may not appear “typical” after AF ablation. However, the effects of LA ablation on the Ablation of Atrial Fibrillation at the Time of Cavotricuspid Isthmus Ablation in Patients With Atrial Flutter Without Documented Atrial Fibrillation Derives a Better Long-Term Benefit Article Jan 2011 Catheter ablation of atrial fibrillation has evolved from ablation of arrhythmogenic foci within the pulmonary veins (PV) to complete electrical isolation of the PV, often guided by perimetric mapping with a multi-polar loop catheter positioned at the rim of each of the PV ostia. 1– 4 Adding an ablation line connecting the inferior margin of the ostium of the left inferior PV (LIPV) to the mitral annulus appears to increase the success rate of treating atrial fibrillation by catheter Effect of right atrial isthmus ablation on the occurrence of atrial fibrillation: observations in four patient groups having type I atrial flutter with or without associated atrial fibrillation (Abstr). J Am Coll Cardiol A typical left atrial (LA) flutter may occur as a proarrhythmic complication of LA ablation of atrial fibrillation (AF).

Methods Background Catheter ablation of left atrial linear lesions is an effective treatment option for perimitral flutter and is often used as a substrate modification approach for persistent atrial fibrillation. The two most popular mitral isthmus lines are those of the anterior or the posterior mitral isthmus. A comparison of these two mitral isthmus ablation approaches is still pending. Methods A linear ablation of the right atrial isthmus was performed during coronary sinus pacing (n = 13), atrial flutter (n = 6), or both rhythms (n = 4). Because of recurrent spontaneous induction of atrial fibrillation, ablation was performed during sinus rhythm (without coronary sinus pacing) in one patient.
